    Entanglement entropy in generalised quantum Lifshitz models 
    Angel Ramelli, Juan Fernando; Giangreco Puletti, Valentina; Thorlacius, Larus (Springer Science and Business Media LLC, 2019-08-01)
    We compute universal finite corrections to entanglement entropy for generalised quantum Lifshitz models in arbitrary odd spacetime dimensions. These are generalised free field theories with Lifshitz scaling symmetry, where the dynamical critical exponent ...

    Entanglement in Quantum Lifshitz Theories 
    Angel Ramelli, Juan Fernando (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2020-11)
    In recent years, the study of entanglement properties of quantum field theories has led to deep insights in fields as diverse as quantum gravity and condensed matter physics. Originating as effective field theories for certain quantum dimer models, the ...

    Logarithmic negativity in quantum Lifshitz theories 
    Angel Ramelli, Juan Fernando; Berthiere, C.; Giangreco Puletti, Valentina; Thorlacius, Larus (Springer Science and Business Media LLC, 2020-09)
    We investigate quantum entanglement in a non-relativistic critical system by calculating the logarithmic negativity of a class of mixed states in the quantum Lifshitz model in one and two spatial dimensions. In 1+1 dimensions we employ a correlator ...
